AUTOMATIC ROTARY ENGINE.

To all whom 'it Vnay concern:

Be it known that I. Honra ARTHUR KING.' a citizen of the United States, residing at- Colton, in the county of San Bernardino and .State of California, have 'invented a nexv Aand useful Automatic Rotary Engine, of .which the following is a specification.

Hy invention relates to improvements in )ny-invention are, first, to provide an im' proved counter-pressure-balanced revolving thereto; second, to provide a valve disk or f carrier arranged to directly actuate one or l more revoluble cylinder-heads; third, to proi vide a motive-fluid chest intermediate the. annular cylinders of a rotary engine, with l means-for regulating the passage of the motive-fluid to said cylinders; fourth, to provide means for starting the engine vvhen the i piston-headsare at any point.; fifth, to provide means for readily reversing the engine by interchanging the inlets and exhausts; sixth, to provide muffler engines on the engine shaft with means for conveying the? exhaustotive-fiuid from' the engine cylinders th eto; seventh, to provide for an inif tial comaression of the motive-Huid before it enters the motive-fluid chest of the engine; l eighth, to provide improved means for packing the rotary parts. I attain these objects and others which will be apparent from the j i'ollovvinfi description, by mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section through my engine; Fig. 2 is a cross-section on the line y-y of Fig. 1; Fig. 3 is a side elevaf tion of one of the piston disks; Fig. at is a side elevation of the regulator or regulating disk.- with the mechanism for changing its l position; Fig. 5 is a side.l elevation of the reverser or reversing disk. together with the i mechanism for changing its position; Figs. 6 and 7 are sectional vieivs along the line f 6 6 of Fig. 4, showing the position of the regulator and reverser when operating the engine in opposite directions; Fig. 8 is a longitudinal section showing my engine arj ranged Without the inufllers and illustrating especially one manner of securing tightl jolnts at the peripheries of the packing rlngs and valves: Fig. f is a cross-section on the lines -S or auf of Fig. S, showing the motive-finiti passages through the reverser and their relation to the inlet and exhaust V ports, together with the mechanism Specification of Letters Ratent.

for changing the position ofthe reverser; Figs. 10 and 11 are cross-sectional views through the valves, regulators, and reversers on the line mg--g of Fig. 9, vshowing the relation of the lfluid passagesl therein; Fig. 1'2 is a detail cross-section through the same parts and the valves and valve-carrier; Fig. 13 is a cross-section on the linel Z--Z of'Fig` 1: Fig. 14 is a cross-section through one of the piston-disks; Fig. 15 is a side-elevation of one of the regulators: Fig. 16 is a detail vievv of a portion of the regulator and showing the mechanism by which its position may be varied for starting the engine when the piston-heads are in different positions; Fig. 17 is a perspective view of the engine casing; and Fig. 18 is an elevation of a piston-disk showing a modified form of piston-head.

Referring to the drawings, my yengine comprises a series lof concentric cylinders or chambers, the central valve-chamber I3, constituting the motive-fluid chest into which the compressed motive fluid is introduced. A valve-carrier or disk L, rotates within the valve-chamber I?. having sprocket teeth upon its periphery which engage the pinions P, mounted in a recess in said valve chamber and secured to shafts which carry the rotary cylinder-heads or abutments fu. The annular valve-rings L', L?. are carried `,by

f the dis'k L upon either side of thelsprocket teeth, and are pressed outwardly to form tight joints againstthe reversing disks L3 by means of springs S, passing through apertures in the disk. The valves are provided \vith suitable apertures or passages to cooperate with the ports and fluid passages through the reversing disks.

` Upon either side of the valve-chamber are the cylinders Within which rotate the pistondisks C. provided with opposite pistonheads which may be solid\or integral with the disk, as shown in Fig. 18, but are preferably formed as shown in Figs. 3 and 14. having a roller 117;' bolted at M to the piston disk so to be adjustable toward or from the periphery thereof, the packingrings V beingbent or sprung outwardly as f shown at V to form a housing for the roller and constitute the main portion of the piston-head. The packing-rings V surrounding the periphery of the piston-disks are preferaoly beveled as shown in Fig. I, and:

are pressed outwardly b v springs S. I`L

prefer to make the piston-disks hollow, as shown at m, and having their hubs splined to the engine shaft.

The revoluble abutments -n are provided .with recesses u2, as shown -in Fig. 13, to receive and permit the piston-heads E to pass. In order that the abutments shall always lit snugly against 'the periphery or' the pistondisk, I provide rollers i", bearing upon the periphery of the abutments and adjustably secured in the casing by means of the supporting bolts, As an alternative construction, I may arrange bolts 9, which bear against the arbor of the cylinder-heads as shown in Fig. 9. In this manner, I am enabled to take up any Wea-r that may occur during the operation of the engine and insure close joints at all times.

The Walls A, which separate the chamn bers or cylinders, are provided with, ports I,I2, which constitute inlet and exhaust ports. Y Between the Walls A and the annular valve-rings L', L2, in the valve-chamber I3, arethe regulating disks L3, and the reversing disks L4. The regulating disks L3 are illustrated inFigs. l and 15. rFliese disks are provided With elongated slots Awhich cooperate With thefports through the reversing disks to determine the length of time the motive-fluid shall enter the cylinder, and their position may be varied at will by ymeans ofthe controller handle N, see Fig. 16. The reversing disks L4 are illustrated in Fig. 9, and are provided with passages H and ports I4. When theports I4 are brought into coincidence with the ports I2, serving as inlets, the elongated passages H will then be in communication Wit-h ports I, serving as exhausts, and vice versa,

as appears from an inspection of Fig. 9. In either position the passages H will be in communication with one or the other of the exhaust passages I-I, H2, leading lthrough the casing Wall. The position of the reversing disks may be changed to reverse the engine by means of the handle Gr. VIn Fig. 5, the' reversing disk is shown as made of two sectors in skeleton form, and in the space between the sectors, a tube O is led to the shaft for the purpose of introducing lubricating oil. I

The relation of the ports and passages in the valves, reversing and regulating disks, and in the walls of the cylinders will be ap'- parent from the detail sectional vievv taken along the line c2-m2 of Fig. 9, as shown in Figs. 10 and 11; While the change in positionof-the regulating disk necessary to reverse the engine is shown in Figs. 6 and taken on the line 6-6 of Fig. 4:.

The operation of my engine will be apparent' from' the foregoing-description. rEhe motive-fluid is drawn .in through a supply through valve R" and compressed and forced by the compression pump E. thrcngh the @nasce pipe R2 into the valve-chamber I3, whence it passes through the openings in the valverings L, L2, the elongated passages-in the regulating disks L3, the apertures I4 in the reversing disks L", and the ports I or I2 in the cylinder walls into the cylindersupon either side of the valve-chamber, and is eX- ploded at the proper instant by the contact of the piston-heads With the spark-plug contacts conventionally illustrated at y. IVhen my machine is operated as a compound. engine, as shown in Fig. 1, the exhaust gases flow through the passages H' or H2, into'the expansion chambers l5, upon either side of the main cylinders, but when the engine is not provided with expansion chambers, as illustrated in Fig. 8, the exhaust gases immediately discharge through the exhaust passages H', H2.

In order that thecylinder may be cleansed after each impulse, l. provide pump or conipressor cylinders for alternately forcing air thereinto, as illustrated on the right of Fig. l. The air is drawn in through valves R4, and after being compressed by the recipro` eating pistons R3, is forced through valves R5 leading into the cylinders.

It will be evident to engineers and others skilled in this art, that various changes may be made in the arrangement of parts Without departing from the spirit of my invention.
